Patent number: 6732400Abstract: A wiper system (1) for vehicles, having at least one wiper lever assembly (7) that has at least one wiper arm (26) and that has a first pivot lever (9) that can be coupled in a manner fixed against relative rotation to a stationary first shaft (19) and a second pivot lever (11) that is freely rotatable about a stationary second shaft (23), is proposed. The first pivot lever (9) is connected via a first joint (15) and the second pivot lever (11) via a second joint (17) to the coupling element (13). The wiper system (1) furthermore has a drive device (29), which has a drive shaft (31) disposed at a distance from the first and second shafts (19, 23); with the aid of the drive shaft, at least one toggle link (37) can be shifted in oscillating fashion, and the toggle link (37) is connected via a joint (43) to a coupling part (45) that is coupled to the first shaft (19) in a manner fixed against relative rotation.Type: GrantFiled: June 12, 2001Date of Patent: May 11, 2004Assignee: Robert Bosch GmbHInventor: Joachim Zimmer

Patent number: 6708365Abstract: The drive apparatus for a wiper system (10) has a reversible wiper motor (18), a lever drive mechanism connected with a wiper (12), which includes a drive lever (36), e.g. a cross guide rod, and a four-bar wiper lever (40) connected with it, and a coupling mechanism (20) for coupling the lever drive mechanism with the wiper motor. The coupling mechanism (20) includes a crank (22) attached to the wiper motor (18), a coupling rod (24) pivotally connected to the crank (22) and in articulated fashion to guide rod (26) pivotally supported on a vehicle body. A joint rod (28) is pivotally connected to the coupling rod (40) and the drive lever (36) to drive the lever drive mechanism and hence the wiper (12) with the drive motor via the coupling mechanism (20).Type: GrantFiled: March 19, 2001Date of Patent: March 23, 2004Assignee: Robert Bosch GmbHInventor: Joachim Zimmer

Publication number: 20040049875Abstract: The invention is based on a wiper system (10) having a mounting plate (12), on whose mounting plate tube (14) a wiper bearing (20) is disposed on one end and a cast part (16) is disposed on the other, and a first bearing housing (22) for a second drive shaft (26) and a second bearing housing (28) for a control shaft (30) of a four-bar lever linkage are integrated with the cast part, and the second drive shaft (26) is driven by a wiper motor (32) via a motor crank (36), a drive element (44), and a bearing rocker (46). It is proposed that the wiper motor (32) is disposed as a reversing motor on the passenger side, and its motor shaft (34) is disposed on the cast part (16) in the vicinity of the second drive shaft (26), between the second drive shaft (26) and the control shaft (30), and the drive element (44) is embodied as a coupling plate.Type: ApplicationFiled: October 7, 2003Publication date: March 18, 2004Inventor: Ulrich Metz

Publication number: 20040034959Abstract: A pivot holder includes a tubular main body, which rotatably supports a pivot shaft therein, and a securing portion, which is integrally formed with the main body and extends from an outer peripheral surface of the main body, and a plurality of engaging grooves. A water shield cap includes a tubular portion, which is fitted to the outer peripheral surface of the main body of the pivot holder, a water receiver, which extends radially outward from the tubular portion, and a plurality of engaging projections. The engaging projections of the water shield cap are engaged with the engaging grooves of the pivot holder to limit axial movement and rotational movement of the water shield cap relative to the pivot holder.Type: ApplicationFiled: August 8, 2003Publication date: February 26, 2004Inventor: Yoshinori Nakamura

Publication number: 20040034958Abstract: This invention relates to windshield wiper system and method which utilizes a flexible member to account for compression loads in excess of a predetermined load, such as 30 percent, greater than a maximum load for the flexible member. The system utilizes a flexible pultruded composite material having a relatively low modulus of elasticity, yet relatively high elongation characteristics. The flexible arm bends to facilitate preventing damage to components in the wiper system when a compressive load applied to the flexible member is in excess of the predetermined load.Type: ApplicationFiled: July 19, 2002Publication date: February 26, 2004Applicant: VALEO ELECTRICAL SYSTEMS, INC.Inventor: Harry Charles Buchanan,

Patent number: 6691367Abstract: The invention relates to a wiper apparatus in which a pair of pivot axes are provided, one pivot axis at the central portion and the other pivot axis one side portion in the left and right direction of the window surface. In the invention, wherein the rod rush angle formed by a link arm, which rotates the pivot axes clockwise and counterclockwise, and a link rod can be made as small as possible. The second pivot axis at one side portion is disposed so that the plane, including the swinging locus, of the second link arm, that is coupled to the corresponding second pivot axis, and the axial line of the second link rod, in the lengthwise direction, are made roughly parallel to each other.Type: GrantFiled: February 16, 2001Date of Patent: February 17, 2004Assignee: Mitsuba CorporationInventor: Takashi Hoshino
